The leaf springs 17 which frictionally engage ythe shutters may conveniently be mounted on the inner face of the facing 25.

Copcrating with providea cuttingfblock 18 adapted to fit vsnugly in the seat accurately positioned 1l oftheframe 10 and preferably provided upon its face with a sheet of brass 19 or thelike to form a suitable ground for the cutting knife. W'ings 20 extending outward from kthe cutting block engage the shoulders 21'of the frame and aid in supportingthe block at the aperture l1. VGruides'22 at two adjacent sides of the block afford alright angular'abutment against which the mat 23 to be cut is upon the block to register with the vslideseat 11. e The manner in which the device is used is readily understood. The operator first positions a slide in the seat 11 in the frame 10.

' He thereupon adjusts the several shutters with the mat blank 23` in position 15 acrossthe face of the slide to determine the exact exposure field 16 for the latter. After this field hasy been determined, the slide is removed and the cutting block 18, thereon,

is yplaced in the seat'll and the mat cut along the edges of the shutters 15. Itis obvious that upon the removal of the cut mat from the block 18, the exact lield 16 which the operatordesired, has been cut from ythe mat and the latter may be at once adjusted upon and secured to the slide in well known manner. i j v f Y n Obviously if it is not desired to cut the mat on the` block 18, it may be marked with apencil which in this event, would be guided along the edge'of the shutters 15 to indicate the field 16 upon the mat blank. The'latter would thenbe removed from the block 18 to Y a cutting board or the like and cut out along the marked lines.V .Y j V ne obvious advantage of the present device is that the use of ruledmats is entirely unnecessary. Any opaque paper of proper size may be placed upon the cutting block andcut or marked in accordance with the field 16 outlined by the shutters. The old uncertain practice of guessing at the field or measuring it out by rule is entirely replaced by tie present much speed/ier andv certain operation ofadjustmg the shutters' directly with relation to the slide to obtain the' desired artistic effect, and then cutting' or marking the mat blank directly from the field ,so outlined by the shutters. Y

. The invention has been described with special relation to the cutting of mats for standard size lantern slides. Obviously it may be employed however for mattingk pictures, or plates of any size if the frame and cutting block are made of suitable size or adjustable to various sizes. The precise construction of the frame shown may be variously modified to give added strength or lightness or to improve the means for holding the plate, cutting block etc. without departing from what I claim as my invention.

` claim as my invention 1. A matting device of the character described, comprising an apertured frame having means for temporarily supporting an image bearer at the frame aperture, shutters adjustable across the frame aperture to determine the desiredV exposure field of the image, in combination with a carrier for a mat blank adapted to support the latter in juxtaposition to said shutters after the removal of the image bearer and in a position substantially in register with that occupied by the image bearer While win the frame, for the purpose described. j j

matting device of the character described, comprising an apertured frame with seat for temporarily supporting an image bearer at the frame aperture, shutters adjustable across the frame aperture and adjacent the said seat, in combination with a carrier for a mat blank adapted to support the latter in juxtaposition to said shutters after, the removal of the image bearer and 1n a position substantially in register with that occupied by the image bearer while seated-in the frame, for the purpose described.

3. A matting device of lthe character de- `for-the purpose described.

1l.. A matting device kof the character described, comprising anapertured frame havmg a ,seat for temporarilyA supporting an image bearer at the frame aperture, and shutters adjustable across said frame aperture to determine the desired exposure fie for the image, in combination with a cutting block adapted to carry a mat blank and plaeeable in the said seat after the removal of the image bearer.

5. A matting device of the character described, comprising an apertured frame having a seat for temporarily supporting an image bearer at the vframe aperture,` and shutters adjustable across said frame aperture to determine the desired exposure fiel for the image, in combination with a cutting block adapted to carry a mat blank and placeable in the said seat after the removal of the image bearer, together With a metallic cutting face on said block.

6. A matting device of the character described, comprising an apertured frame having a seat for supporting an image bearer at the frame aperture, and a surrounding seat for a sheet of ground glass, and shutters adjustable across the frame aperture Copies yof this patent may be obtaine for ve cents each,

the image bearer but adjacent the seat for that for the on the side thereof opposite ground glass.

7. A matting device ofthe character described, comprising an apertured frame havtemporarily supporting an image bearer at the frame aperture, and

etermine the desired field of display of said image, in combination With a carrier or a mat blank having means for detachably supporting themat blank thereon andadapted, after the removal ofthe image bearer, to hold the said mat blank in juxtaposition tc the shutters and in a position substantially in register With that occupied by the image bearer While in the frame.

In testimony whereof I lhave signedmy name to this specification, in the presence of two sub'scribiribg Witnesses.
